From a46e5ef6216ca8c6023593c6c24dfb62be49df10 Mon Sep 17 00:00:00 2001 From: Erik Johnston Date: Mon, 24 Nov 2014 10:50:28 +0000 Subject: SYN-163: Add an order by rowid to selects. This should fix the bug where the edges of the graph get returned in a different order than they were inserted in, and so no get_event no longer returned the exact same JSON as was inserted. This meant that signature checks failed. --- synapse/storage/_base.py | 15 ++++++++++----- 1 file changed, 10 insertions(+), 5 deletions(-) (limited to 'synapse/storage/_base.py') diff --git a/synapse/storage/_base.py b/synapse/storage/_base.py index fd5b2affad..4881f03368 100644 --- a/synapse/storage/_base.py +++ b/synapse/storage/_base.py @@ -246,7 +246,10 @@ class SQLBaseStore(object): raise StoreError(404, "No row found") def _simple_select_onecol_txn(self, txn, table, keyvalues, retcol): - sql = "SELECT %(retcol)s FROM %(table)s WHERE %(where)s" % { + sql = ( + "SELECT %(retcol)s FROM %(table)s WHERE %(where)s " + "ORDER BY rowid asc" + ) % { "retcol": retcol, "table": table, "where": " AND ".join("%s = ?" % k for k in keyvalues.keys()), @@ -299,7 +302,7 @@ class SQLBaseStore(object): keyvalues : dict of column names and values to select the rows with retcols : list of strings giving the names of the columns to return """ - sql = "SELECT %s FROM %s WHERE %s" % ( + sql = "SELECT %s FROM %s WHERE %s ORDER BY rowid asc" % ( ", ".join(retcols), table, " AND ".join("%s = ?" % (k, ) for k in keyvalues) @@ -334,7 +337,7 @@ class SQLBaseStore(object): retcols=None, allow_none=False): """ Combined SELECT then UPDATE.""" if retcols: - select_sql = "SELECT %s FROM %s WHERE %s" % ( + select_sql = "SELECT %s FROM %s WHERE %s ORDER BY rowid asc" % ( ", ".join(retcols), table, " AND ".join("%s = ?" % (k) for k in keyvalues) @@ -461,7 +464,7 @@ class SQLBaseStore(object): def _get_events_txn(self, txn, event_ids): # FIXME (erikj): This should be batched? - sql = "SELECT * FROM events WHERE event_id = ?" + sql = "SELECT * FROM events WHERE event_id = ?
